Dell wi-fi catcher conflict with gaming mouse

Hello,
Howdy, I have a Dell Inspiron 1525 w/ vista, I recently bought a gaming mouse with 15 programmable buttons. One button specifically, when I press it the Dell wi-fi catcher screen pops up. I tried to disable the wi-fi catcher abilitity, which does disable the swich function on the side of the laptop, but screen still pops up when I hit the specific key on mouse. I have reinstalled software, reasigned key function. I have another laptop that is the same , and it does not do it on that one. The game is World of Warcraft, and the mouse is designed for that game. The key function on mouse and wi-fi catcher screen command must be crossing somehow. ?????

Please help,
